Myllaena procidua Casey View in CoL Figs 124-131

Diagnosis.

This species may be distinguished by its body shape (Fig. 124), small size (about 1.6-2.3 mm long), antennal articles VII–X elongate (Fig. 124), and the shape of the median lobe of the aedeagus and the spermatheca (Figs 125, 126, 131). It is worthy to note that the median lobe of Myllaena procidua is similar to that of Myllaena kaskaskia Klimaszewski and Myllaena vulpina Bernhauer, but the shape of the spermatheca differs significantly and has much better diagnostic features for identification of this species.

Distribution.

Bionomics.

The Newfoundland specimens were taken on the gravel banks of a stream and a river. In New Brunswick, adults occurred along river (clear water) margins among cobblestones set in sand and fine gravel at the water’s edge, or among gravel at the edge of the water ( Webster et al. 2009). Adults were located by turning over cobblestones and larger pebbles ( Webster et al. 2009). In New Brunswick, adults were collected during May, June, July and August, by turning over cobblestones and pebbles ( Webster et al. 2009).
